The code uses `//go:embed` which actually embeds a fake filesystem into the binary. It’s really easy to miss that part, but it truly is one single binary, despite seeming to reference files by paths.

Oh dang, that's neat! Thank you!

No it isn't. You can try compiling from source and running it yourself: https://git.j3s.sh/j3s.sh/tree/c4517e8484a68c734d2f17c17c546...
